  • Rails routes and model woes

    - by Chris Maness
    I'm a little new to rails sorry if this seems basic Alright so here's the deal I'm creating an application that will have many users and all the users have many songs. However when I try to create a song I get the following error:No action responded to 1. Actions: create and new and my browser is at the url: http://0.0.0.0:3000/users/1/songs which is not the correct route it should have redirected to songs/create Here is my controller code: class SongsController < ApplicationController def index @user = current_user @songs = @user.songs end def new @user = current_user @song = @user.songs.build end def create @user = current_user @song = @user.songs.build(params[:song]) if @song.save redirect_to user_song_url(@user, @song) else render :action => "new" end end end If anyone can help I would greatly appreciate it.

  • How can I request local pages in the background of an ASP.NET MVC app?

    - by flipdoubt
    My ASP.NET MVC app needs to run a set of tasks at startup and in the background at a regular interval. I have implemented each task as a controller action and listed the app-relative path to the action in the database. I implemented a TaskRunner process that gets the urls from the database and requests each one at a regular interval using WebRequest.Create, but this throws a UriFormatException. I cannot use this answer or any code that plucks values from HttpContext.Current.Request without getting an HttpException with the message "Request is not available in this context". The Request object is not available because my code uses System.Threading.Timer to do background processing, as recommended here. Here are my questions: Is there really no way to make local web requests within an ASP.NET web app? Is there really no way to dynamically ascertain the root path to the web app even using static dependencies in ASP.NET? I was trying to avoid storing the app's root path in the database (as FogBugz does with its "Maintenance Path"), but is this best option?

  • Ruby on Rails - Adding variable to params[]

    - by miligraf
    In the controller, how can I add a variable at the end of a params[]? If I try this I get an error: params[:group_] + variable How should it be done? Edit per request Ok, I have a form that sets groups of radio buttons with names like this: group_01DRN0 Obviously I have different groups in the form (group_01AAI0, group_01AUI0, etc.) and the value is set according to the radio button selected within the group: Radio button "group_01DRN0" could have value of "21" or "22" or "23", radio button "group_01AAI0" could have value of "21" or "22" or "23", etc. In the DB I have every code (01DRN0, 01AAI0, 01AUI0, etc) so I want to select them from DB and iterate in the params value so I can get the radio button group value, I've tried this with no luck: @codes=Code.get_codes for c in @codes @all=params[:group_] + c.name end Thanks.

  • Stack recommendations for small/medium-sized web application in Python

    - by reto
    I'm looking for some recommendations for a python web application. We have some memory restrictions and we try to keep it small and lean. We thought about using WSGI (and a python webserver) and build the rest ourself. We already have a template engine we'd like to use, but we are open for some suggestions regarding the whole request handling (the controller). The application has to run in a single process and the requests have to be processed with multiple threads. We've looked at django, but we are a not sure if it fits into our memory budget. Your feedback is very welcome! Cheers, Reto

  • ASP.NET MVC2 - specific fields in form pass via a specific object?

    - by ile
    In database I have Contacts table: ContactID (int) FirstName (varchar) LastName (varchar) ... XmlFields (xml) // This field is xml type To create a new contact, I created two classes - one for regular fields and other to display fields from XmlFields field. In Controller, I have following: public ActionResult Create(Contact contact, FormCollection collection) ... Regular field I catch with contact object and those that need to be stored as xml in XmlFields I try to catch with collection object. Problem is that collection object catches all fields, so I wonder if it is possible to isolate xml fields when posting to a specific object so that I can easily manipulate with them. I need this in separated objects because these xml fields are going to be generated dynamically and will be different for every user. Thanks in advance, Ile

  • ASP.NET MVC Routing

    - by creativeincode
    My website uses categories and sub-categories. I'd like the follow mapping: /Category/Fruit /Category/Fruit/Apples But if I use the below: routes.MapRoute( "Category", // Route name "Category/{category}/{subcategory}", // URL with parameters new { controller = "Entity", action = "Category" } // Parameter defaults ); I get a 404 for /Category/Fruit however /Category/Fruit/Apples works ok. I'd like /Category/Fruit to work as well but I can't add another route with the same name. How do I get around this? Thanks in advance.

  • Can't get Angular Dart Router to work

    - by JesterXL
    I've tried this syntax in AngularDart 0.11.0: Angular Dart passing data from route service into a controller module.value(RouteInitializerFn, configureRoutes); void configureRoutes(Router router, RouteViewFactory views) { print("configureRoutes"); views.configure({ 'login': ngRoute( path: '/login', view: 'login/login.tpl.html'), 'today': ngRoute( path: '/today', view: '/today/today.tpl.html') }); However, my routing function never seems to get called. I've used both a print statement and breakpoint to no avail. When I attempt to call it like so: WorkoutLoggerApplication(this.rootScope, this.router) { print("WorkoutLoggerApplication::constructor"); new Future.delayed(new Duration(seconds: 2), () { router.go("login", {}); }); } I get: Bad state: Invalid route name: login I've tried 0.10.0, but no dice. I've also tried 3 varieties of the new bind function format, both also don't seem to ever fire the routing function.

  • AJAX server calls on a JSF-centric app

    - by Konrad Garus
    I'm building a JSF 2 application. I wanted to integrate it with jQuery, e.g.: $.getJSON(contextPath + '/something', function(data) { // ... }); I need contextPath/something to return data in JSON. How can I do it? I know I can assign another servlet to this URL, but this approach does not seem to scale well. One could use a more scalable approach with a front end controller (e.g. Spring Web MVC), but I really wanted to write this in Java Enterprise stack. What other options are there?

  • Ruby class variable is reset after rails app initialized

    - by Phuong Nguy?n
    I tried to assign a class static variable like this class QueryLogger < Logger @@query_logger_default_instance = nil def self.default_instance # Use global variable because static variable doesn't work @@query_logger_default_instance ||= self.new(STDOUT) end end In initializers folder of my rails app, I added a file with this code block ActiveRecord::Base.logger = QueryLogger.default_instance In a request (action of controller), I make a call to this: QueryLogger.default_instance. My assumption is that the call to default_instance will always report the same. However, it does not. Now I try to watch stuff in NetBeans by setting breakpoint inside default_instance. Thing happen as expected, the default_instance get called twice, one due to the initializer block and one due to the call to my action. Surprising thing is, in both times, @@query_logger_default_instance report nil inside NetBeans inspector. The first nil report is correct, but the second shocked me. It's look like static variable gets reset after rails app initialized. Is there some magic there?

  • Reject (Hard 404) ASP.NET MVC-style URLs

    - by James D
    Hi, ASP.NET MVC web app that exposes "friendly" URLs: http://somesite.com/friendlyurl ...which are rewritten (not redirected) to ASP.NET MVC-style URLs under the hood: http://somesite.com/Controller/Action The user never actually sees any ASP.NET MVC style URLS. If he requests one, we hard 404 it. ASP.NET MVC is (in this app) an implementation detail, not a fundamental interface. My question: how do you examine an arbitrary incoming URL and determine whether or not that URL matches a defined ASP.NET MVC path? For extra credit: how do you do it from inside an ASP.NET-style IHttpModule, where you're getting invoked upstream from the ASP.NET MVC runtime? Thanks!

And if questions and answers are presented differently whats the best way to go about this.

  • Rails and jQuery - how do you get server-side validation errors to your view after an ajax request

    - by adam
    Ive searched this site but questions are usually regarding doing client-side validations or for different frameworks. I have a tasks list whose items can be edited inline. Upon submitting the inline edit form the item is updated all thanks to jQuery, ajax and rails. But I want to handle bad input from the user. HTML requests redisplay the view and errors are displayed thanks to rails helpers. But how do I insert that information after an ajax call? Heres my update method in my controller def update @task = Task.find(params[:id]) respond_to do |format| if @task.update_attributes(params[:task]) flash[:notice] = 'Task was successfully updated.' format.html { redirect_to(@task) } format.xml { head :ok } format.js else format.html { render :action => "edit" } format.xml { render :xml => @task.errors, :status => :unprocessable_entity } #format.js ...hmmm... either go to js.erb file or do stuff inline end end end

  • A PHP object server for business logic

    - by Matthieu
    I wonder if such a thing is possible or even exist : In the MVC pattern, I would like to have the Model part to be persistant in memory, instead of reloading my instances at each execution. So I want only the Controller and View part to be executed. Is there any solution of server that would provide PHP objects (just like a Mysql server provides data records), and that keeps these objects in memory ? A problem would be also : how to have a constructed query to get objects ? Maybe PHP Linq ?

  • How are people popping their UINavigationController stacks under a UITabBarController?

    - by RexOnRoids
    I have four UINavigationControllers assigned each to a tab in a UITabBarController. Each UINavigationController manages a UIViewController, which may itself branch out into other UIViewControllers below it hierarchally. My question is, in a case in which a user, under one tab, has navigated to a UIViewController that hierarchally BELOW the main UIViewController managed by the UINavigationController, and then the user pushes a different tab, and then goes back to the original tab, HOW can I make it so that the user is presented with the main UIViewController managed by the UINavigation controller? and not the page where he left off?

I'm just not finding what is the correct kind of exception and it's namespace. The error must be coming from the DB, so... Any ideas? Thanks

    - by Matt
    So I took some php code and turned it into a calendar with a helper to make a simple calendar.

How do I get this to work with my params hash. Thanks for the help.

  • How is it possible the class inheritance in namespaces using Ruby on Rails 3?

    - by user502052
    In my RoR3 application I have a namespace called NS1 so that I have this filesystem structure: ROOT_RAILS/controllers/ ROOT_RAILS/controllers/application_controller.rb ROOT_RAILS/controllers/ns/ ROOT_RAILS/controllers/ns/ns_controller.rb ROOT_RAILS/controllers/ns/names_controller.rb ROOT_RAILS/controllers/ns/surnames_controller.rb I wuold like that 'ns_controller.rb' inherits from application controller, so in 'ns_controller.rb' file I have: class Ns::NsController < ApplicationController ... end Is this the right approach? Anyway if I have this situation... in 'application_controller.rb' class ApplicationController < ActionController::Base @profile = Profile.find(1) end in 'ns_controller.rb' class Ns::NsController < ApplicationController @name = @profile.name @surname = @profile.surname end ... '@name' and '@surname' variables are not set. Why?

    In my Rails 2.3 application, the following routes were working properly map.ajax 'ajax', :controller => 'widgetresponse_controller' , :action => 'getWidgetJson' When I migrated to Rails 3, I tried a number of new routes, to get this working but none of them worked. 1. match 'ajax' => 'widgetresponse#getWidgetJson', :as => :ajax 2. match 'ajax' => 'widgetresponse_controller#getWidgetJson', :as => :ajax 3. get 'widgetresponse/getWidgetJson', :as => :ajax 4. get 'widgetresponse/getWidgetJson' Its a very basic question to ask, but I don't know what I am doing wrong.

  • How do i style a JSON feed in my view?

    - by stephenmurdoch
    My rails app gets the following JSON feed from mixcloud and sticks the results into my index page At the moment when I do this, the entire contents of my feed are displayed unformatted in one big blob of scary looking text (without the curly JSON brackets) I only want to display specific values from the feed in the view. From the feed in question lets say for simplicity that I just wanted to display all values with a key of "url" In case I'm doing something wrong here's my code: # podcast controller def index # I'm using a class method to get the feed @feed = Podcast.feed end # podcast model def self.feed feed = JSON.parse(open("http://api.mixcloud.com/alivefrommaryhill/feed").read) end # index.html.haml .feed = @feed I can't figure out how to style the results and display only certain items from the feed. Is my approach wrong?

  • Combining features from other projects in an ASP.NET MVC application

    - by Katie D
    Hello, I am writing an ASP.NET MVC application that combines a set of features from existing applications. The new application is suppose to use UI features and logic created (especially for this purpose) in the existing applications. For that reason I wanted to create in the existing applications some kind of a "blackbox" that I will be able to drop in my new application along with a matching connection string, and it will work independently, binding data on it's own. I thought about using partial views, but I am having trouble with passing the model data to it, since the controller of the new application should not know about the model of the existing applications. I can not use ASP.NET WebForms, since my application should be a "postback-less" application, and ASP.NET AJAX toolkit or frameworks alike are out of the question. Any help would be greatly appreciated. Thank you, Katie

  • Detect when a UITableView is being reordered

    - by Mike Weller
    I have a UITableView backed by an NSFetchedResultsController which may trigger updates at any time. If the user is currently reordering rows, applying these updates will cause an exception because the table view has temporarily taken over and you get an error like Invalid update: invalid number of rows in section [...] How can I detect when the user has started moving a cell so I can delay updates caused by the fetched results controller? There don't seem to be any table view delegate methods to detect this. This delegate method: - (NSIndexPath *)tableView:(UITableView *)tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath { Doesn't get called when the user initially detaches the first cell, only when they actually move it somewhere else.

  • asp.net mvc custom model binding in an update entity scenario

    - by mctayl
    Hi I have a question about model binding. Imagine you have an existing database entity displayed in a form and you'd like to edit some details, some properties eg createddate etc are not bound to the form, during model binding, these properties are not assigned to the model as they are not on the http post data or querystrong etc, hence their properties are null. In my controller method for update , Id just like to do public ActionResult Update( Entity ent) { //Save changes to db } but as some properties are null in ent, they override the existing database fields which are not part of the form post data, What is the correct way to handle this? Ive tried hidden fields to hold the data, but model binding does not seem to assign hidden fields to the model. Any suggestions would be appreciated

  • numberOfSectionsInTableView is requested in/after viewDidLoad ONLY if tableview is empty

    - by Ben Packard
    A simple tableviewController, empty. A modal that can be launched from a button. No data in the data source for the tableview, and no rows displayed. I open the modal, use it to add an item, and return to the tableview controller. The tableview updates itself automatically, and the new row is displayed. I add a second item. The table view does NOT update automatically. I can tell by logging inside numberOfSectionsInTableView that even if I go to add the first item and cancel, the tableview refreshes - it asks for the number of sections, rows, and the cell to display (if there is one). But not if there is one pre-existing row in the table. I've scoured my code but can't find anything that would cause the tableview to know when the first item is added, but none afterwards. Any ideas? EDIT - I have further narrowed my issue so will close this shortly and post a more specific question

  • How to access Grails domain classes in Java service layer?

    - by batmannavneet
    How can I use grails domain classes (which is in groovy) in service layer which is in Java/Spring. When using the grails MVC, everything is fine as I can use controller to access domain objects and call CRUD and other dynamic methods on them. But, what I am wondering is is there a clean way to do it from Java - say the service layer. For example, I may want to develop a reporting framework where I need to use domain objects to access the DB. I Hope the question is clear. This should be a standard problem that everybody must have faced in a reasonably sized project. I am just wondering how it is solved..maybe I am missing something here. thanks.
